金剛三昧經論 2.3

2.3

論曰：菩薩觀行成就之時，知自觀心順理修行，非有生心非無生心，亦非有行亦非無行，但為離增益邊故假說為無生，不於有生生心、不於無生生心故；為離損減邊亦假說為行，雖非有有行之行，而非無無行之行故。是故立名〈無生行品〉。

The commentary states: When a bodhisattva's contemplative practice is perfected, one knows one's own contemplative mind conforms to principle in cultivating practice, being neither a mind that has arising nor a mind that lacks arising, and also neither having practice nor lacking practice. Solely to depart from the extreme of superimposition, it is provisionally spoken of as non-arising, because one does not give rise to a mind in the presence of arising, nor does one give rise to a mind in the presence of non-arising. To depart from the extreme of deprecation, it is also provisionally spoken of as practice, because although it is not a practice that possesses practice, neither is it a practice that lacks non-practice. Therefore, it is titled the 'Chapter on the Practice of Non-arising'.
